Both documents old, but useful. Section 7 of the 'Hard-Disk-Upgrade' mini
howto discusses moving the data. Moving that much data is going to take
time - lots of it. At 50 Megabytes/second, 400 Gigs is about 2.25 hours
assuming nothing else is happening. When upgrading disks, it's often a
good idea to be running in 'single user' mode, to minimize other tasks
and reduce the chance of someone trying to access either disk at the
same time.

For max speed, connect the drive internally. To avoid opening your case,
conenctiong and disconnecting drives, put the second drive in an USB box.
This is, however, much slower.

If you're comming from NTFS, you don't even have to worry about maintaining
ownership or rights. Just use rsync, with enouigh parameters to keep the
date.
:
rsync -var source/ dest/

This has the advantage you can allways interrupt the process. When started
again, it will resume where it left off.

Be patient, have fun. I just did 200 GB when I replaced a drive.
